Dielectric Properties of PbNb2O6 up to 700°C from Impedance Spectroscopy
Figure 19
Activation energy () for DC conduction in different temperature regions. in symbol name indicates the use of peak technique of finding relaxation time, and indicates the cross technique case. Here, 2 stands for fit to 2 temperature regions and 3 for 3 temperature regions fit, the chosen temperature region of fit being indicated by corresponding horizontal bar through the symbol.
